Last I looked into this, Tesla itself hasn't sad anything about it being available (that I'm aware of). Just they filed the paperwork with the state, which is how news sites got the information. Based on said documentation it would allow Tesla Insurance to "start as early as 10/20/2022".
Likewise, there hasn't been any updates on Tesla's site, to include Florida in the state availability list (Tesla Insurance - Available States).
I'm definitely hoping they start insurance before December (when I have to renew my policy ).
Edit: Looking through that webpage's code, the last time it was published was 10/14/2021, so it hasn't been updated in awhile.
